The pop ballad was written by Andrew Frampton, Wayne Wilkins, and Paul Herman along with Bedingfield for her debut album, Unwritten (2004).

[1] While collaborating with Andrew Frampton, Wayne Wilkins and Paul Hermam in London, England, they composed "I Bruise Easily", which was inspired by a relationship Bedingfield had recently ended.

[3] PopMatters stated that the song was a "worthy slow-burner highlighted by Natasha's soul-baring lyrics",[4] and RTÉ Entertainment commented that the "soulful ballad" was "both impressive and broadranging.

"[5] Andy Gill of The Independent gave it a very strong review, stating that the song contained some of the album's strongest lyrics that "deals sharply with the difficulties of finding Mr Right".

Because it was released as the fourth single, success was very limited since many consumers had already purchased the album, which at the time had been certified triple platinum in the United Kingdom.

The track "Ain't Nobody", performed with Bedingfield's brother Daniel and recorded live at the BRIT Awards, is a cover version of the Chaka Khan and Rufus 1983 single.
